teaching you things like what "understand" means is a large task. are you willing to put in effort by e.g. reading a book chapter, and answering questions to identify what you do and don't already understand about the matter?
Almost certainly not. I take this as confirmation that “understand” is the key misleadingly-simple word in your quote.
